Add "--force" and "--quickly" flags to bin/lipsum

Summary:
Ref T12319.

  - Lipsum can trash an install by creating a lot of junk that's hard to get rid of, so we're cautious about letting you run it. Add a `--force` flag if you're sure you know what you're doing. This makes the edit/test cycle a bit easier when actually writing Lipsum generators.
  - Lipsum normally sleeps for a second before creating objects, to give users more control over how much stuff they create and limit the amount of damage caused by mistakes. Sometimes, you want to generate a LOT of stuff because you want to reproduce a performance/scale issue (like T12319). Add a `--quickly` flag to generate objects as fast as possible.
  - When loading random users (used as authors, assignees, etc), also load user settings so we can `ConduitCall` with them.
  - Allow generators to return a PHID instead of an actual object (more convenient for Conduit-based generators).

Test Plan:
  - With next change, ran `lipsum generate badges --force --quickly`.
